The Julia Language

In recent versions (can't say from exactly when), there seems to be an off-by-one error in dcc.DatePickerRange. I set max_date_allowed = datetime.today().date(), but in the calendar, yesterday is the maximum date allowed. I see it in my apps, and it is also present in the first example on the DatePickerRange documentation page.

When I save any of my notebooks as HTML in Safari, the output file is always called true.html. The name of the output file is correct in Chrome, though.

• MacOS 10.15.7
• Safari 14.1.2
• Pluto v0.15.1
• Julia 1.7.0-beta3.0

The error message below is not friendly or helpful for new users. (It came up on Discourse, and it is one of the more frequent questions we get asked.)

Perhaps something like:

`MOI.ScalarQuadraticFunction{Float64}`-in-`MOI.EqualTo{Float64}` constraints are
not supported by this solver.

When I use Plots.jl with PyPlot backend, I get the following dep warning message:

┌ Warning: `getindex(o::PyObject, s::AbstractString)` is deprecated in favor of dot overloading (`getproperty`) so elements should now be accessed as e.g. `o."s"` instead of `o["s"]`.

The following code gives a segfault with Makie 0.15 and Julia 1.6.1 (also reproduced with 1.7-beta2):

using Makie

xs = range(150, 160, length=100)
ys = range(7, 9, length=100)
points = [(x, y, 0.0) for x in xs for y in ys]
x, y, z = map(i -> getindex.(points, i), 1:3)

flags = (153 .< x .< 153.5) .& (7 .< y .< 7.3)
surface(y[flags], x[flags], z[flags]);

Starting Julia

I found that function mod2pi is not implemented yet, but mod works. Is there any list of implemented functions? Minimal working example is:

using Zygote

# This is working
gradient(x -> mod(x, 2pi), 1.)

# This is not
gradient(x -> mod2pi(x), 1.)

In order to profile and optimize the current inference server architecture and best tune its hyper-parameters for various applications, it would be very useful for AlphaZero.jl to have a mode where it outputs a debugging timeline in which it is possible to easily visualize when each worker submits an inference request, when it gets an answer, and when inference concretely runs on the GPU (along wi

In Exercises 10.1, the outer product in Take the outer product of a vector v with itself and assign it to variable cross_v should be cross product.

The basics of DiscreteSystem exists now, but the little details around it need to be finished.
